Data centre operators are increasingly looking at vanadium batteries to manage energy flows. And it could be the answer to the expanding, energy-hungry artificial intelligence infrastructure sector, with data centres rising around Australia's major cities. Vanadium batteries are quite different from better known lithium-ion batteries used in common household electronics and electric cars, bikes and scooters. "But grid operators don't like that - they don't want to see very high power loads swinging, so data centre operators globally are asking themselves, 'How do we deal with that'?" Asked by AAP what data centre interest the company was seeing, he said the AI infrastructure build-out was moving much faster in the US than in Australia.
